Deep fryer selection?

Yup second posting today. Trying to avoid paper/presentation due Monday--supermassive black holes.
BigMan wants a deep fryer for xmas. I have a feeling he is trying to kill me with clogged arteries. Do anyone have one they love? Do you use it enough? What size? Those small ones are cute but do they work or does one have to toil over the hot oil too long?
Thanks!
